Influence of TiO2 Film Thickness on the Electrochemical Behaviour of Dye-Sensitized Solar Cells

International Journal of Electrochemical Science, 2011
A commercial TiO2 powder was deposited on F-doped SnO2 (FTO) glass substrates by a spray coating technique with different thicknesses (6, 10 and 14 µm) to be used as photo-anode in dye-sensitized solar cells (DSSCs). N3 dye was adsorbed on each TiO2 film

Spectroscopic detection of halogen bonding resolves dye regeneration in the dye-sensitized solar cell

Nature Communications, 2017
Dye-sensitized solar cells rely on molecular dyes to absorb light and conduct electrons. Parlane et al. show that weak forces such as hydrogen bonding can be responsible for the dye regeneration step of solar cells and have an impact on the photovoltage ...

Dual Porphyrin Sensitized Photocatalytic System for Visible‐Light‐Driven CO2 Reduction

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Dual porphyrin–sensitized TiO2 enables efficient visible‐light CO2 reduction by integrating Zn‐porphyrin photosensitization with urea‐functionalized Fe‐porphyrin catalysts. Immobilization enhances charge separation, activity, and durability, while tuning electron donor and proton availability reveals key aspects that influence this catalytic conversion.
